Vibration Analysis

A reliable real-time vibration monitoring system for Cristal Pigments UK Ltd

THE CHALLENGE—We have worked on a wide range of projects for our client Cristal Global and our knowledge of vibrating systems has enabled us to develop a bespoke vibration monitoring system. Early projects with them led to the realisation that two of their support structures were in trouble because of continuous vibration imposed by violent chemical reactions in the process vessel. THE [...]

Pipework Analysis

Substantiation of Piping Package

The Challenge: DC White were commissioned to substantiate a piping package to several codes, ASME B31.3 for the pipework and API 610 for the nozzle loads. A previous report found that the loads acting on the pump suction and discharge nozzles were failing to meet the requirements of API 610. The recommended modifications were to place the pump on a sliding baseplate and include an additional support [...]

Failure Analysis

Marine engine bearings failure analysis

DC White have recently been requested to carry out inspections of two large marine diesel bearings by a major fleet operator. The bearings failed prematurely and the fleet operator sought an independent opinion in order to assist in negotiations with the engine manufacturers. The first bearing was a main bearing and the second a crosshead bearing. The first had run for 15,000 hours and the second for [...]

Seismic assessment in research facility

FEA & Design Improvement Case Study We were asked by our client to perform a seismic assessment of a door for a biological laboratory in New Zealand. The primary purpose of the door was to act as an airtight seal between the 'clean-room' environment and the rest of the research facility. Because of the likelihood of earthquakes in such a seismically active part of the world, it [...]

Expert Witness

Valves Seals and Gearboxes

Valves Transco experienced leakage problems on large 36" pipeline ball valves at a pressure reduction station. Valve leakage was investigated as part of a proposed legal action against the valve manufacturer. The leakage was found to be due to wear and compression set of the 'O' rings used to seal the valve seats. BP Clair Engineering Assessment of Sub Sea Isolation Valve Actuator Failure. Assisted [...]
